predict.textmodel_wordfish: Prediction from a textmodel_wordfish method

Description

predict.textmodel_wordfish() returns estimated document scores and confidence intervals. The method is provided for consistency with other textmodel_*() methods, but does not currently allow prediction on out-of-sample data.

Usage

# S3 method for textmodel_wordfish
predict(
  object,
  se.fit = FALSE,
  interval = c("none", "confidence"),
  level = 0.95,
  ...
)
# S3 method for textmodel_wordfish
coef(object, margin = c("both", "documents", "features"), ...)
coefficients.textmodel_wordfish(object, ...)

Value

coef.textmodel_wordfish() returns a matrix of estimated parameters coefficients for the specified margin.

Arguments

object

a fitted wordfish model

se.fit

if TRUE, return standard errors as well

interval

type of confidence interval calculation

level

tolerance/confidence level for intervals

...

not used

margin

which margin of parameter estimates to return: both (in a list), or just document or feature parameters
